NASA counts down to launch first spacecraft to ‘touch Sun’

Although much of the Sun's structure is still something of a mystery to us, the PSP is full of possibility.

Why is it so hard? That's because Earth is barreling through space at 19 miles per second, or 67,000 miles per hour. This same element is found on the nose of space shuttles, to protect them when they enter or leave the Earth's atmosphere.

This will be within 6 million kilometres of the sun's surface, closer than any other spacecraft has been before.

Scientists said the Parker Solar Probe that will come 3.83 million miles million miles from the surface of the sun.

"According to a statement from Nasa, the probe is due to orbit within six-and-a-half million kilometres of the Sun's "surface", where the probe will "(face) heat and radiation unlike any spacecraft in history". "I think the Parker Solar Probe is a fascinating mission". The 65-minute launch window for the mission opens at 3:33 a.m. EDT on Saturday. He added that, the sun temperature vary at times depending with the amount of gas being burn hence estimating the punishment the solar probe will receive was harder and almost impossible by from the help from several scientist, the probe was created to adjust to certain levels of thermal and radiant heat.

Why Argentinian Senate voted against legal abortion
Senators in Argentina voted down a bill Thursday that would have legalized abortion on demand until week 14 of a pregnancy. Last June, Pope Francis-who is Argentinian-compared the practice of abortion to Nazi eugenics and ethnic cleansing.

Russian Federation hits back at 'unacceptable' sanctions as rouble tumbles
Skripal and his daughter were poisoned by the Novichok military-grade nerve agent in the English city of Salisbury in March. Russian Federation denies any role in the attack.

Over 100 rockets fired into Israel from Gaza
Israel's defense chief said last month that Gaza's only commercial border crossing, Keren Shalom, would reopen if calm persisted. One Israeli soldier was killed by a Gaza sniper during this period.

The Parker Solar Probe will ride atop one of the most powerful space rockets we have today, the Delta 4 Heavy. About the size of a small auto, it weighs a mere 1,400 pounds.

The project was proposed in 1958 to a brand-new NASA, and "60 years later, and it's becoming a reality", said project manager Andy Driesman, also of Johns Hopkins, which designed and built the spacecraft. And it needs to be, because it takes an enormous amount of energy to get to our final orbit around the Sun. It's the fastest any man-made object will have ever traveled and the probe will likely hold that title for a long time.

Set to launch early Saturday, the Parker Solar Probe is as heat-resistant as a spacecraft gets, essential for exploring our star closer than ever before. After passing past Venus to get onto the right trajectory, the probe should make its first visit to the Sun in November 2018. The spacecraft will make a total of seven orbits around Venus. "And that allows us to shrink our orbit and go closer to the sun than anything has been before". They can also affect satellites' orbits and lifetimes, causing trouble on Earth when we aren't able to receive the signals we need.

Guarding the spacecraft and its four instruments against temperatures, reaching 2,500 degrees, is a 4.5-inch thick carbon-composite shield.
